I'm working with Amazon VTL (Virtual Tape Library) and Bacula v 5.2.6 which
functions well and can run concurrent jobs to multiple tape drives just
fine.
I want to speed up restores for DR purposes and make use of the 10 virtual
tape drives VTL gives you.
I am not sure if bacula supports restoring to multiple tape drives at the
same time and haven't been able to find anything in the documentation as
such.
I have created multiple restore jobs and ran them concurrently just fine but
each restore job waits for the first tape drive to complete before running.
JobId Level Name Status
======================================================================
423 RestoreFiles.2014-10-13_19.35.32_03 is running
424 RestoreFiles2.2014-10-13_19.35.53_04 is waiting on Storage
"Tape1"
So running concurrent restores doesn't provide any net benefit as they can
only run 1 at a time.
If anyone has any information regarding running restore jobs at the same
time using multiple tape drives please let me know. Thanks in advance.
My restore job configs look like this:
##
Job {
Name = "RestoreFiles"
Type = Restore
Client = backup02
FileSet = "Full Set"
Pool = Disk
Messages = Standard
Where = /mnt/restores
Maximum Concurrent Jobs = 10
Prefer Mounted Volumes = no
}
Job {
Name = "RestoreFiles2"
Type = Restore
Client = backup02
FileSet = "Full Set2"
Pool = Disk
Messages = Standard
Where = /mnt/restores
Maximum Concurrent Jobs = 10
Prefer Mounted Volumes = no
}
